N ON -REFILLABLE BOTTLE.

Application filed June 9, 1911.

To all whom it may concern:

Be it known that I, SAMUEL S. WILLIAM- soN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in vented a certain new and useful Improvement in N on-Refillable Bottles, of which the following is a specification.

My invention relates to new and aiseful improvements in non-refillable bottles and has for its object to provide safety devices which will automatically close a valve upon its seat and hold the same in this position except when the bottle is inverted for the purpose of pouring out the contents.

A further object of my invention is to provide means for permitting air to seep into the bottle below the valve, to prevent the formation of a partial vacuum within the bottle by changes of temperature.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which- Figure 1, is a vertical section of a portion of a bottle, showing my improvements applied thereto. Fig. 2, a side elevation of the keeper. Fig. 3, a top view of the valve. Fig. 4, a view similar to Fig. 1, the major portion being broken away, showing the locking member in the form of a pin instead of a ball; and Fig. 5 a plan view of the cap for holding the air plug in place.

In carrying out my invention as here embodied, (1) and 8 a hollow valve fitted to slide within said neck, the conical portion 4 thereof be ing adapted to close upon the valve seat 5 formed at the base of the neck.

6 represents the keeper, the outer portion of which may be in the form of the mouth of a bottle, and the lower portion of this keeper is adapted to fit within the neck and is held in place by a metal ferrule 7 fitting over the flange 8 and pressed into the annular groove 9 formed along the upper end of the neck as clearly shown.

Patented Feb. 2, 1915. Serial No. 632,246.

From the mouth of the keeper lead passages 10 and the series of lugs 11 which are formed with the keeper prevent the forcing of a wire or other implement downward to the operating mechanism. The under surface of the keeper is recessed in the form of a cone as indicated at 12 and from the top of this cone recess extends a cylindrical recess 13 in which is located a spring 14 adapted to bear upon the locking member 15, which in Fig. 1 is shown as a ball and in Fig. 4 as a pin.

16 is a ball interposed between the ball 15 and the valve 3 and adapted to be crowded sidewise by the ball 15 so as to firmly hold the valve upon its seat. Upon the lower portion of the valve is formed a cage 17 in which is placed a small ball 18 and the inner walls of this cage are of such contour as to retain this small ball within the cage until the bottle has been inverted to a position that will cause the mechanism to unlock the valve, after which the small ball will drop the full length of the interior of the valve and striking upon the head thereof will jog the valve loose from its seat, thus overcoming any tendency of the valve to stick upon its seat.

Where a bottle partially filled with liquid is subjected to changes of temperature, it is well known that within the bottle and this partial vacuum of course tends to hold a valve upon its seat and often prevents the pouring of liquid from the bottle. This I overcome by utilizing a plug 19 of material having fine pores therein, such as earthenware, and securing the same in the housing 20 by the cap 21 and by corrugating this cap as clearly shown in Fig. 5, air will have free access to the upper surface of the plug and should there be the slightest vacuum formed in the bottle, a certain portion of this air will seep through the plug and relieve said valve but the liquid will not flow through the plug on account of the fineness of its pores.

In pouring any portion of the contents from the bottle, the latter is inverted sufficiently to cause the ball 16 to overbalance the action of the spring, compressing the latter by forcing the ball 15 downward into the cavity 13 which will free the valve and permit it to drop off its seat, allowing the contents to fiow downward around the fiat sides of the valve, which latter 18 square in a partial vacuum is formed cross section as shown in Fig. 3 for this purpose.

In turning the bottle back toward its normally upright position, as soon as the inclined wall of the conical recess 12 reaches the horizontal, thus taking all of the weight of the ball 16 from OH the spring, the latter will recoil, forcing the ball 15 upward, thus crowding the ball 16 ing the valve upward against its seat, or should the valve be of such weight as to prevent this action at this time, the further return of the bottle will bring the inclined surface of the cone shaped recess at an angle to the horizontal, which will cause the ball 16 to tend to roll down said surface, adding its Weight to the action of the spring toward forcing the valve upward. The valve being hollow and sufficiently buoyant will fioat upward against its seat should the bottle be inverted to the position where the ball compresses the spring and the weight of the ball 16 and the ten sion of the spring are determined, so that the valve will be forced upward by the spring and ball before the bottle reaches a position where the valve would not float closed, should an attempt be made to force liquid within the bottom.

If found desirable, the mechanism may be assembled and secured within the neck of the bottle before the latter is originally filled and it may thereafter be filled through the housing 20 before the porous plug 19 is secured in place. In this device the spring let coacts with the balls 15 and 16 to hold the valve firmly upon its seat and prevent the jumping of the valve by vibration, yet in no wise interferes with theopening of the valve when the bottle is in position to pour the contents therefrom.

that certain liquids improve with age when not hermetically sealed and the ventilating plug 19 will permit this action to take place upon the contents of the bottle after the latter has been corked.

Of course I do not wish to be limited to the exact details of construction as here shown, as these may be varied within the It is well known copies of this patent may be obtained for five cents each, by addressing the to one side and liftlimits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful, is-

1. In combination with a bottle, a hollow valve fitted to slide in the neck of said bottle and close upon a suitable seat, a keeper secured in said neck having a conical recess in the lower end thereof, a ball located between said keeper and the valve, a locking member adapted to travel in a recess formed in the keeper and coact with the ball to hold the valve closed, and a spring adapted to force the ball sidewise through the medium of the locking member, said spring being of such tension that the ball will depress it when the bottle is inverted as and for the purpose set forth.

2-. In a non-refillable bottle, a valve mounted in the bottle adapted to move rectilineally therein and coact with ayalve seat, a keeper having a concaved portion in its inner end and a cylindrical recess in communication therewith, a ball mounted between the valve and keeper and lying within said concavity, a locking member situated in the cylindrical recess and adapted to move rectilineally therein, and resilient means mounted within the recess co-acting with the locking member for causing the latter to co-act with the ball and force said ball sidewise for locking the valve upon its seat.

3. In a device of the character stated a valve seat, a valve fitted to said valve seat, a ball normally resting on the top of the valve, a keeper fitted. over the ball, a locking member fitted to slide in the keeper on the axial line of the valve to automatically lock and unlock the ball by the change of position of the device and a spring fitted in the keeper adapted to co-act with the locking member.

In testimony whereof, I have hereunto aflixed my signature in the presence of two subscribing witnesses.
